How to Replace a Garbage Disposal

One of the handiest appliances in your kitchen is probably something you don’t think about very often, until it stops working. Then your garbage disposer becomes one of the scariest plumbing appliances for an inexperienced DIY homeowner. With its gnashing teeth hiding under the kitchen sink drain, not many DIYers unfamiliar with this appliance want to go anywhere near the task of replacing a garbage disposer.

To help remove some of the mystery and terror associated with the replacement of the garbage disposer, Friedman’s Home Improvement is here with some helpful tips to make this a do-able Weekend Warrior Project. First, know that this project requires some moderate do-it-yourself skills and some basic knowledge of electrical wiring:

    1. If you do not have a disposer set up already, call an electrician to set up the wires first. If you are replacing an existing garbage disposer, the following steps are appropriate.
    2. Turn off the power and water running to the garbage disposer.
    3. Disconnect the drain trap from the garbage disposer’s discharge tube, the slip fittings to the drain, and the dishwasher inlet hose (if one is attached).
    4. Remove the old garbage disposer by turning clockwise. Be careful not to let it fall on you.
    5. Turn the garbage disposer upside down and unscrew the electrical cover plate from the bottom.
    6. Disconnect the electrical cable connector from the garbage disposer.
  1. Pull out the wire nuts and unscrew the wire from the green ground screw.
  2. Remove the mounting assembly if you are replacing the old garbage disposer with a new one.
  3. If you are setting up the dishwasher to drain through the garbage disposer, remove the plastic drain plug from the disposer.
  4. Install the new garbage disposer in the reverse order that you took the old one out.

Voila! You’re done, and everyone who used the garbage disposer (before it died) will thank you for your hard work getting it to work again. Celebrate by inviting your friends over for drinks so you can show off your handywork!  However, don’t get too crazy putting weird garbage down the drain, or you may have to resort to our previous blog:  “How to Unclog a Sink Drain”.
